President Trump has threatened to remove four Federal Reserve governors appointed by former President Biden, alleging their nominations were auto-signed. Speaking at a rally in Pennsylvania, Trump claimed he would investigate the use of automatic signing machines for these appointments and has tasked Treasury Secretary Scott Bessent with the inquiry. Legal challenges are anticipated if any Senate-confirmed appointments are invalidated. The Federal Reserve has not commented on the matter. The use of auto-signers, a practice dating back to the 1940s, was legally affirmed by the Department of Justice in 2005. Trump has also criticized the Fed's slow interest rate cuts and suggested potential leadership changes after Chair Jerome Powell's term ends in May 2026.
